rev 1.3

Low Power, 5V/3.3V, µP Reset, Active LOW, Open-Drain Output

General Description

Applications

The ASM1233D-L/1233D/1233M are voltage supervisors with

low-power, 5/3.3V µP Reset, with an active LOW, open-drain

output. Maximum supply current over temperature is 15µA for

3.3V devices and 20µA for 5V devices.

The ASM1233D-L/1233D/1233M generates an active LOW

reset signal whenever the monitored supply is out of tolerance.

A precision reference and comparator circuit monitors power

supply (V_CC) level. The tolerance are 5%,10% and 15%. When

Single board computers

Typical Operating Circuit

an out-of-tolerance condition is detected, an internal power-fail

signal is generated which forces an active LOW reset signal.

After V_CCreturns to an in-tolerance condition, the reset signal

V_CC

remains active for 350ms to allow the power supply and system

microprocessor to stabilize.

Microprocessor

The ASM1233D-L/1233D/1233M is designed with an open-

drain output stage and operates over the extended industrial

temperature range. These devices are available in compact

SOT-223, SO-8 and TO-92 packages.
